Most killdeer pick the dumbest places for their nests. On pavement, bare ground, on gravel, right by the edge of a street, on bare ground surrounded by grass that is mowed every few days. When I find them, I often need to alert the grounds crew so it can be marked to prevent mowing there until babies are gone. This mama was smart. She chose a spot in the mulch of a bed of native plantings. She blends in and no one will be walking or mowing there. I would not have seen her if she had not let out a short trill to alert me.
